No TACO this time from President Trump … as promised, he’s filed a defamation lawsuit over the Wall Street Journal story claiming he wrote a racy 50th birthday note to Jeffrey Epstein.

Trump filed Friday in federal court in Florida — just about 24 hours after the WSJ story dropped. According to the docs, obtained by TMZ, he says the Journal falsely passed off as fact he’d drawn the image of a naked woman, and signed his name “Donald” to mimic pubic hair … when they had access to information showing their story was false. He does not say what that information is.

The suit insists there is “no authentic letter or drawing,” and the Journal concocted the story “to malign President Trump’s character and integrity and deceptively portray him in a false light.”
